improper chemical action of the vaporizing substances.

Another object is the provision of a deviceof this character including a tube for discharging fumes into the vaporizing container, the tube preventing the fuming from, entering the vaporizing container.

Another object oi the invention is the provision of a device of this character in- .cluding a coil for the passageot fumes having a trap arranged to prevent passage of the fuming liquid into the vaporizing container.

Another object is the provision of a device of this character in which the fuming liquid trap also serves as a connecting me1nher for the sections ol 'the coil so that the parts of the coil may be easily cleaned.

Another objectis the provision of a de vice or" this character having a fuming liquid trap from which the liquid can be readily removed without cisengaging the tube from the container.

A still further object is the provision of a device of this character having an inspiratory tube including means which prevents the entrance of liquid or air into the container.

lVith these and other objects in view, the invention consists in the improved construction and arrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a vertical elevation and sectional view of a vaporizer constructed in accordance with the invention.

Fig. 2 is a top plan view.

Fig. 3 isa detail and sectional view of the fuming liquid trap.

Referring to the drawings, 5 indicates a container adapted to receive a medicated Patented Notnlfi, 1920. Serial No. 343,713. 1

I V plurallty oi necks 6, which are closed by. means of stoppers!- and 8. The stopper 7 is provided with an opei'iing 9,.which extends from end to end and 18 adapted ceptacle- 10 in which fuming, liquid to support a resuch' as hydrochloric acid is deposited.

The stopper 8, is provided with a pairof openings 11 and 12, the. tube 13 being mounted in the opening '11, and extending through the stopperinto the. container and terminating adjacent the bottom beneath the level of the solution therein The upper end portion 14 of the tubec13 is extendedin right angular relation to the body of the tube and then downwardly and inwardly to provide 'a projecting partial. coil 15. Another tube 16 is provided and serves as anvextension ofthe tube 13. The end 17 of the tube 16 is disposed in the receptacle l0 in spaced relation thereto, while the remaining end 18 is extended in right angular relation to the body of the tube 16 and then bent into a partial coil 19.: The end 18 or" the coil 19 and the end of the coil 18' are connected to each other by means or" a'trap 20. This trap is constructed in the form of a-T, the branches of the T connecting the ends of thetubes, while the stem 21' of the T is threaded'and provided with a cap 22, the stem serving asa trap to intercept any fuming liquid that might pass throughthe tube 16, :the'cap22 permitting the liquid to be readily removed from the trap without disconnecting the tubes 16 and'13 or removingsaid tubes from the container.

Disposed in the opening 120 5 the stopper 8' is an inspiratory tube 28, which terminates at the'bottoof thestcpper and has its upper portion inclined and provided with a valve chamber 2%, in which 25 is freely-mounted. Extending from the valve chamber 24'is a tube 26 which forms an extension of the inspiratory tube. The end of the tube is'provided with a nozzle 27.

In the operation of, the device, the medicated solution is deposited in the container, the solution surrounding the lower end of the tube 13. A fuming liquid such as hydrochloric acid is deposited in the receptacle 10. When the user inhales through the inspiratory tube 13, the suction at the same time causes fumes torise from the fuming liquid in the receptacle 10 to pass upwardly through the tube 16 around the a ball valve solution in the lower portion thereof. The top of the container, is provided with a coil,'down the tube 13 .into the medicated solution, where a chemical action takes place to produce vapors which rise to the top of the container and are discharged therefrom with the same suction. this operation, should the force of inhaling be so great as to cause the fuming liquid to enter the tube 16, the trap will receive the liquid and permit only the fumes thereor to 'passthrough the remainder of the coil and down through the tube 13 into the medicated solution.

without disengaging liquid from the fumes thereof.

From the foregoing, it will be readily seen that this invention provides a novel form of vaporizer which through the provision of the coil in the tubes conveying the fumes, prevents improper chemical ac tion so that vapor of the proper quality and strength is produced in the container.

' Any liquid that may have collected in the trap 20 can be readily removedtherefrom the tubes 13 and 16 from the container'by simply removing the cap 22 from the trap.

The invention having been set forth, what is claimed as new and useful is:

1. A vaporlzer of the character described comprising a container, means, for closing the open end of said container, a tubeineluding a coil. supported by said means,

said tube having a trap, an outlet forsaid trap, one end of said 0011 extending into the container terminatingadjacent the bottom'thereof, the other end extending into 'a fumingliquidreceptacle carried by the container.

2. 'A vaporizer'or the character described comprising a container, means for closing the open end of said container, a tube including a coil supported by said means, said tube having a trap, an outlet for said trap, one end of, said coil extending into the container and terminating adjacent the bottom thereof, the other end extending into a fuming liquid receptacle carried by the container, said coil separating the fuming 3. A vaporizer of the character described comprising a container, means for closing the open end of said container, a tube including acoil supported by said means, said tube having a trap, an outlet for said trap,

During into said receptacle,

receptacle in spaced one end of said coil extending into the con I tainer and terminating adjacent the bottom thereof, the other end extending into a fuming liquid receptacle carried by the container, said trap cooperating with the coil to prevent the passage of fuming liquid through the tube disposed in the container; 4. The combination with a container having openings in its top, a stopper for each 7 opening, a liquid receptacle carriedby one ofsaid stoppers, of a tube coiled adjacent its intermediate portionto provide a fume and liquid separator, the long end portion of said tube being mounted in another of said stoppers and extending through the same into the container, the short end portion extending in the direction of the long end portion and in parallel relation thereto, a trap carried by said coil and vapor outlet means carried by said second mentioned stopper.

5. The combination with a container having openings in its top portion, a'stopper for each opening, a fuming liquid receptacle carried by one of said stoppers, of a another of said stoppers, 7

tube supported by one end portion of said tube extending through the stopper into the container, the other end portion being partially coiled, a second tube having one end disposed in said A relation to the wall thereof, the other end of said second mentioned tube being partially coiled, a trap connecting the coiled end portions of the tubes'to each other, said trap having an outlet and means for closing said outlet.

6. A vaporizer of the character described comprising a container, stoppers for-said container, 'a fuming liquid receptacle supported by one of said stoppers, a sectional coiled tube having one end disposed in the receptacle, the other end extendingthrough another of said stoppers and terminating adjacent the lower portion of the container,

a fuming liquid trap in said coil, said trap having an outlet, and a tube extending throughthe last mentioned stopper, said tube including a valve, and a nozzle on the other end of said tube. I r
